Multiqueue tun/tap interface
Clash Royale CLAN TAG#URR8PPP
I am trying to understand how Multiqueue tuntap interface works. Following the instructions provided at: https://www.kernel.org/doc/Documentation/networking/tuntap.txt
I was able to create multiple queues. However, I don't know how to check the queus status and where they are created. I tried:
$ tc -s class show dev tap0
(where tap0 is my tap interface), I see around 255 queues, even for a single ioctl call with IFF_MULTI_QUEUE flag. So probably I am looking at the wrong place. Here is the snippet of the output of the above command:
class mq :1 root
Sent 4741 bytes 37 pkt (dropped 0, overlimits 0 requeues 0)
backlog 0b 0p requeues 0
class mq :2 root
Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
backlog 0b 0p requeues 0
.
.
.
class mq :ff root
Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
backlog 0b 0p requeues 0
class mq :100 root
Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
backlog 0b 0p requeues 0
Secondly, I am not sure how to steer packets to these queues based on some filter or classifier using TC or anyother tool.
